Percentage Type 1 Shortcut Tricks

 

Example 1: In school examination Harish scored a total of 870 mark out of 1250. what is his approximate % in the exam ?
Answer : 870 x 100 / 1250 = 69.6%

 

Example 2: The difference between 49% of a number and 14% of the same number is 8920. What would be the 70% of that number ?
Answer : 49% – 14% = 8920
35% = 8920
75% = 8920 x 70 / 35 = 17840

 

Example 3: Rajiv is given a exam and scored 35 marks in Bengali, 42 in geography, 38 marks in English, 26 marks in science and 46 in History. The maximum marks a student can score in each subject is 100, What would be the percentage did Rajiv get in this exam ?
Answer : 35 + 42 + 38 + 26 + 46 = 187
187 x 100 / 500 = 37.4%

 

Example 4: P’s height is 25% less than that of Q, how much percent Q’s height is more than that of P ?
Answer : Ratio of heights of P : Q = 75 : 100
So, percentage of Q’s height is more than that of P = 25 x 100 / 75 = 33.33%

 

Example 5:
In test examination its required to get 50% marks to pass. Roshan got 360 marks and he failed by 65 marks. What would be the maximum marks in test examination ?
Answer : 360 + 65 = 425
425 x 100 / 50 = 850.
The maximum marks in test examination is 850.

 

Example 6: In a local forest were 725 lions in past year. In this year has number of lions increased that is 20%. How many lions are there present in this year ?
Answer : past year lions are 725 and 20% increased.
So, 725 x 120 / 100 = 870.
Lions are there present in this year is 870.

 

Example 7:
If the difference between 45% of a number and 3/5th of that number is 18. What is the number?
Solution:
Let the number be a.
Then a x 45% – a x 3/5 = 18
a x 45% – a x 60% = 18 ∴ ( 60% = 60 / 100 = 3 / 5 )
a x 15% =18
a = 100 x 18 = 1800/15 = 120.
Tricks:
we know that 3 / 5 = 60%
45% – 60% = 15 %
15% = 18
= 120.
The number is 120.

 

Example 8:
Find the missing term.
? % of 35 = 672
Answer :
Let x % of 35 = 672
Then, ( x / 100 ) of 35 = 672
672 x 100 = 67200 / 35 = 1920
The missing term is 1920.

 

Example 9:
If 65 percent of a number is 51 less than 4 / 5 of that number. Find the number is ?
Solution:
Let the number be Y.
Then, 4 / 5 Y – ( 65% of Y ) = 51
4 / 5 Y – 65 / 100 Y = 51
15 Y = 5100
Y = 340.
The number is 340.

 

Example 10:
If declaring a length 71.472 Km as almost as possible with three important digits, What would be the percentage error ?
Solution :
Error = ( 71.5 – 71.472 )Km = 0.028.
So Required percentage = ( 0.028 / 71.472 X 100 ) % = 0.039%.
The percentage error is 0.039%.

 

Example 11:
The ratio 6 : 4 expressed as a percent equals to as.
Solution :
6 : 4 = 6 / 4
6 / 4 = (6 / 4 x 100 )%
= 150%

 

Example 12:
Evaluate the Example ?
25% x 280 + 24% x 750
Solution: The percentage error is 0.039%.
25 / 100 x 280 + 24 /100 x 750
70 + 180 = 250

 

Example 13:
A Nokia dealer sold a smart phone at 15% discount on print rate. If the customer paid Rs, 8500 and the printed price is 25% more than its cost price, What is the cost price of smart phone ?

The cost price of smart phone is 8000.

 

Example 14: If income of Harish is 25% more than Prakash, then what % Prakash income is less than that of Harish’s income ?
Answer : we know the formula is = ( increment% / 100 + increment% ) x 100
25 x 100 / 120 = 20% less

 

Example 15:
The difference between 60% of a number and 30% of the same number is 24500. What is 75% of that number ?
Answer :
difference between 60% of a number and 30% of the same number is 24500
60% – 30% = 24500
30% = 24500
24500 x 100 / 30
So, 75% of that number is = 24500 x 75 / 30
= 2450 x 25 = 61250 .
The 75% of that number is 61250.

 

Example 16:
Evaluate the Example ?
58% of 30102 – 32% of 17344
Answer :
17459.16 – 5550.08 = ?
? = 11909.08

 

Example 17:
Evaluate the Example ?
52% of 8540 + 15% of 7860 = ? + 2540
Answer :
4440.8 + 1179 = ? + 2450
5619.8 – 2540 = ?
? = 3079.8.
